RESERVOIR ATTACHMENT FOR PENS Filed Sept. 28, 1926 gwuenki R055 FGearge Patented Feb. 9, 1932 nose n. ebenen, or sEAT'rLE, WASHINGTON RESERVOIR ATTACHMENT FOR PENS Application filed September 28, 1926. Serial No. 138,165.

lilly invention relates to a pen and to a reservoir attachment therefor, and particularly to a construction wherein an under-feeder and an crerfeeder combine to form a main int;

J reservoir, located both abcve and below the pen body, vas heid in its writing position, and cooperate further with each other and the pen te thin down the ink body as it ap preaches the writing tip, in whatever posil tion the pen niay be held or flexed while in use, and te feed the ink thus in condition .fer use to the writing tip of the pen over the upper side of the pen body, in this manner insuring against the formation of a blot by l5 leasen or the inli hanging from the under side of the pen and yet obtaining a large volume in the reservoir to the end that frequent dipmay be obviated.

nderfeeders and overfeeders alone are 20 commonly associiited with pens, and they have frequently been associated together. By reason, in seine cases, of their inl'lenibility, and in other cases, of their arrangement relative to each other and 'to the pen, they have 25 net generally been found satisfactory in co1n- 30 pen is almost certain to cause a blot, for unless the ink is fed to the writing tip along the upper side of the pen, it is almost sure to hang and bleed from the underfeedcr, and to cause too great an excess of inlt, and this is particularly noticeable at the end of a line. ln order to feed the ink properly over the upper side of the pen and to insure its withdrawal from the writing tip at the end of a stroke, an overfeeder must be employed with an iniderfeeder. Further, the two feed ers, cut incre especially the underfeeder, must thin dawn the ink body cl ntained within it and between itself and the pen so that it may pass by capillary attraction through the slit between nibs of the pen and se that it will not bleed or drip by reason of its collective 'weight from the lower end of the feeder. My present invention, therefore, relates especially te a combination between an overfeedcr and an underfeeder, associated with a flexible pen, to properly feed the ink to the writing tip of the pen, and to withdraw it therefreni the lexure on the pen is relieved.

Those features comprising my invention, and which are illustrated in the accompanying drawings will be described hereinafter and particularly defined by the claims terminating this specification.

Figure l is a perspective view showing the form of construction of the feeder.

Figure 2 is a longitudinal section therethrough along a slit between nibs.

Figure 3 is a section on line 3-3 of Figure lit will be observed that in the forni of the pen shown, an overfeeder, generally designated by the numeral l, is located on the upper or convex side of the pen, and extends from a point well up on the pen body towards and which it preferably extends. rlhis extension is indicated generally by the numeral 10. An underfeedcr, generally designated by the numeral 2, lies at the lower or concave side of the pen body, and extends from a point substantially the saine as the overfeeder l, or at least well above the writing` tip, towards the writing tip but stopping short thereof. The lower end 2O of the underfeeder, as illustrated, stops back of the tip 10 of the overfeeder and back of the tip 30 of the pen 3.

It will be noted in Figure 2 that the underfeeder 2, at its tip, approaches and lies closely adjacent, the underside of the pen, generally touching the pen, although this is not essential. The purpose of this is to thin down the body of ink towards the tip of the feeder so that it will pass readily by capil lary attraction through the slit or slits 31 between the nibs but will not be enabled to collect in so heavy a drop that it will bleed or drip from the tip of the underfeeder. rllhe same is true of the overfeeder, and while itis desirable, in connection therewith, it is quite essential with respect to the under` feeder;

It may be pointed out here that the feeders l and 2 may be fixed in position relative to the pen in any suitable manner, as shown herein, but preferably by a flexible mountsubstantially to the writing tip, over ing. For example, a band 11 at the upper end of the overfeeder encircles the pen 3 partially or wholly, and is connected toV the feeder 1 by a flexible neck 13. As shown in Figure 2, it may engage and grip a similar band 21, connected to the unnerfeeder 2 by a flexibleneck 23. This form is designed for use where extreme flexibility in the support for the feeders is desired, and where it is intended that the pen should project but slightly from its holder. The flexible necks 13 and 23 are doubled under so that the bands 11 and 21 lie beneath the respective feeders.

In Figure 1, the overfeederl has been shown as centrally divided by a longitudinally` extending depression 127 which may be formed with relatively steep side walls *whereby Ytwo ink wells 14 are provided at each side of the depression 12, and between the feeder and the back of the pen 3, and the channel 12, if properly formed for the purpose, may receive and retain ink as well. The chief function of the depression 12, however, is `to divide the reservoir into semiindependent ink wells. The edges of the reservoir, as indicated at 15, (see Fig. 3), are spaced somewhat above the pen body so that a. brush or blotter maybe inserted readily for cleaning. Y

i Due to the flexing of thc pen in writing, and to the flexibility of the overfeeder 1, as a whole, on its neck 13, a local reservoir is formed between the tip 10 of the overfeeder and the'upper side of the writing tip 30 of the pen. This localA reservoir communicates with the writing tip 30 through .the slits 31, or equivalent means, and is in communication with the main reservoir lll through the channel l'provided between the lower-end of the feeder 1 and the pen, and along which the inl; is drawn by capillary attraction toward the pen tip. Y

, The underfeeder 2 is formed generally somewhat flat, having side flanges 24C conforming generally to a p lane surface parallel to the writing sheet, but'spaced therefrom.

It also has inwardly directed flanges 25 pro- Y Vid-ing a longitudinal slit 26 down its center.

Y By these means, the pen can be lled by dipping and there are provided channels which are open and accessible for the insertion ofa brush or blotter to clean the reservoir 27, between the feeder 2 and the under side of thep'en. The inwardly directed flanges 25 serve the further purpose of dividingv the reservoir 27 in thesame manner that the depression12separates the reservoir 14. yThe tip of the underfeeder is soplaced relative to the pen, that the inlr is thinned outto a fine film, so that it readily will pass through the slits 31 between nibs, to reach the upper `reservoir. l

The depression 12 is accentuated to the pointthat a slit 17 is formed between two separated flanges 18. Bythis means free access is had to the interior of the upper reservoir for filling and cleaning, and the slot 17 acts as a breather. Y The tip 30 of the pen illustrated in Figure 2 is not bent, although the tip 10 of the overfeeder 1 may be slightly turned up. This, in effect, forms a local reservoir at 33, between the upturned tip 10 and the tip 30 of the pen. The manner of supporting the feeders, with the bent-under bands 11 and 21 illustrated, has been previously described. ItV should not be understood, however, that there is any essential Aconnection between this particular type of feeder and this support; rather, the feeder may be employed with any proper support and the support with any feeder. i

What I claim as my invention is:

1. In combination with a pen, a feeder vattachment therefor extending longitudinally of and generally spaced from the pen, and lying closely against thepen at its tip, and

' means disposed beneath the upper end of the feeder and engageable with the pen body to secure the feeder thereon. l

2. In combination .with a pen, a feeder attachment therefor generally spaced from and extending longitudinally of the pen, feeder securing means engageable with the pen body,

and a connection. between the feeder and that edge of the feeder securing means which is f a bent-under kneck at the upper end of the feeder terminating in a feeder securing means `adapted for securement to the pen body.

11. In combination with a pen having a ilexible writing tip, a feeder attachment therefor comprising 'a band .adapted for ysecurement to the pen body, a fiexiblenec-k extending from the edge of the band farthest -from the pen tip, and a feeder body bent back over the band and extending to the pen tip.
